Technology: breaking the hegemony that monopolizes the world

These small balls are not bulky, each roughly the size of a fist, and are black and white in color. Their appearance is smooth, and whenever they are touched, the surface will sparkle with light.

In fact, these small balls are both sensors and positioning devices.

It can sense the surrounding air temperature and humidity, and the radar device in it will also scan the surrounding environment and output signals to locate the sweeping robot.

Because of the large space, I used six, one in the corners, and two on the walls and shelves in the central area.

"Bring Xiaohao, the sweeping robot equipped with a camera, to turn it on and clean up." Gu Qing picked up the phone and opened the [Boundary Monument].

Zhang Tianhao, a Northeast assistant from Harbin Institute of Technology, pushed over a trash can with a camera.

Press the button in the center of the bucket, and the top of the trash can flashes a red light.

"Hygienist Xiaohao is turning on the machine... detected the owner's [Boundary Monument] program.

Load the current scene information, please pay attention to the sensor status. "

There was a mechanical sound in the trash can, and the six sensors in the factory flashed green.

Gu Qing watched the signs of the six sensors on the screen of the mobile phone change from gray to green, and then the interface in the center of the screen was displayed as a flat map. After all, there are not many sensors.

Conveniently under the screen is the function menu.

There are sweeping functions, sprinkling functions, mopping functions, disinfection functions and smart modes.

Although it is not the first time to clean up, but it is the first time to clean up a space of 200 square meters, so Gu Qing chose the smart mode.

Smart mode—lazy mode, when this mode is turned on, the robot will scan the surrounding environment through the camera, and determine the garbage disposal mode combined with the sensors bound to the outside world, and all its own sensors will be turned on once, and will detect the waste in the air in a short time Dust content of these data.

"The smart mode is starting, please pay attention to protecting precious items, animals, and infants." The mechanical sound sounded.

Then I saw the trash can move. First, the camera rotated to scan the surrounding environment.

Gu Qing can clearly see through the screen of the mobile phone that many garbage and filth are marked with red dots in the robot's field of vision.

hum...

After a few seconds, the tires under the trash can started to move.

Then I saw a trash can starting to spin in circles.

After all, there is garbage everywhere, so it must be cleaned from the bottom,

Zhang Tianhao, a Harbin Institute of Technology graduate who had just pushed this robot in, was very excited at the moment.

Because the design of this robot is his work, although the program and functions have been optimized and changed by Gu Qing, this robot is like a child to him.

So it is called Xiaohao, and Xiaohao started to work normally, so he was naturally excited. Of course, Gu Qing thought there must be a reason for this: if the machine sells well, Zhang Tianhao will get a share of it.

The robot Xiaohao performed very well. First, it cleaned up the larger garbage such as the melon and fruit garbage bags around several square meters, and then started mopping the floor to clean up small particles and liquids.

But the problem came later when this small area was cleaned.

The robot Xiaohao finished cleaning the surrounding ground, and then it went to the next area, and the tires at the bottom inevitably left traces of filth.

After the camera scanned it, Xiaohao started to circle in circles...

Three laps to the left and three laps to the right, it circled back and forth along its own tire marks.

Zhang Tianhao frowned when he saw this scene.

"It's okay, Internet cafes and computers are prone to problems, just restart." Gu Qing comforted him with a smile, then found the robot in the ecological area of ​​the mobile phone software [Boundary Monument], and long-pressed to restart.

At the same time, a red light flashed on the chest of the robot Xiao Hao who was rotating in a circle. After three flashes, the red light disappeared and Xiao Hao stopped moving.

Three seconds later, a red light flickered above Xiaohao's head.

"The restart is quite fast." Gu Qing smiled when he saw this.

"Hygienist Xiaohao is restarting the machine... the master [Boundary Monument] program has been detected.

Load the current scene information, please pay attention to the sensor status. "

There was a mechanical sound in the trash can, and the six sensors in the factory flashed green again.

Gu Qing still chose the old, smart mode.

"The smart mode is starting, please pay attention to protecting precious items, animals, and infants." The mechanical sound sounded again.

Then I saw the robot kid moving again. First, the camera rotated to scan the surrounding environment.

hum...

A few seconds later, the tires under the trash can began to move, but this time the robot did not turn around, but began to clean according to the areas divided by the intelligent program.

The cleaning speed is actually not fast, but this is not manual processing, and there is only one machine. In the middle of the process, the robot opened its own barrel once, pushed out a tightly packed garbage bag, and then continued to work.

The space of 200 square meters has been cleaned by the robot Xiaohao for an hour.

Zhang Tianhao stared intently at its every move. He didn't heave a long sigh of relief until the last garbage bag was pushed out of the barrel.

"Huh, it's finally over."

Gu Qing patted him on the shoulder with a smile, and said, "You big mouse, have you found out the reason for Xiaohao's failure?"

Hearing this, Zhang Tianhao shook his head, then looked at Gu Qing with hope.

For his own boss, he and other college students recruited with high salaries have long admired him. He is simply a genius who is more knowledgeable and talented than his mentor.

Gu Qing did not go around in circles, he pointed to the brand-new factory building and said: "Usually our laboratory is a small space, the amount of information processed is not large, and there are not so many obstacles, so the program tasks are easy to arrange.

But it’s not working in this factory. There are few sensors, the sensing range is not large, and the camera transmits a lot of data. Naturally, the chip needs to process more data, and the tasks increase exponentially, just like a computer with poor performance suddenly running 3A It is normal for a masterpiece to crash or fail to load. Because of this, Xiaohao did not continue to circle around after restarting to collect and process the unprocessed data again. "

Zhang Tianhao thought for a while, then he felt enlightened, and then asked: "Then what should we do? Upgrade the chip? Or increase the number of sensors?"

Gu Qing nodded: "These measures are all possible, but it is recommended that you optimize the program first, that is, accept Xiaohao to optimize the scene data processing, intelligently divide the cleanliness of the ground and the cleaning area, and differentiate the cleanliness level. .

To be more specific, after the large scene is directly divided into small scenes, the cleanliness level is graded, and after cleaning to a level, meticulous cleaning and disinfection are carried out. In fact, we humans also clean in this way, first throwing out large garbage, and then sweeping the floor Dust and then mop. "
